Window cover acting as storm window



May 17, 1966 MA GROSSMAN WINDOW COVER ACTING AS STORM WINDOW Filed Dec.26, 1963 INVENTOR. mim/:off Waff/mm United States` Patent O 3,251,399WINDOW COVER ACTING AS STORM WINDOW Manny Grossman, 1901 HennesseyPlace, Bronx, N.Y. Filed Dec. 26, 1963, Ser. No. 333,460 1 Claim. (Cl.160-180) This invention relates to a window covering device and moreparticularly to a flexible transparent cover for a window that willactas a storm window.

In manybuilding structures, windows loosely fit in l their frames orsash permitting the ingress of cold air, wind and dust, giving rise todiscomfort, increased fuel cost, as well as the burden of more-frequentcleaning operations.

Though the application of conventional storm windows of glass withinwood or metal frames, is well known, such are rigid, bulky and hard tohandle units requiring special fittings in their placement over windowsas well as the utilization of substantial storage space when not in use.

It is accordingly the principal object of this invention to provide aninterior window cover of a flexible, transparent material that can beeasily applied and secured to the inside of a window frame to effect aweather-tight each other by a slight pulling movement.

Another object of this invention is to form`in the flexible, transparentwindow cover, a flap portion forming a part of the transparent cover andhaving separable edges detachably secured to the transparent cove`r suchas to provide an opening therein to the outside.

The invention further consists in the several features hereinafterdescribed and more particularly pointed out in the appended claim.

In the drawing:

FIGURE 1 is a perspective view of the transparent window cover showingdetails of the co-acting fastener strips as well as the openable flapportion.

FIGURE 2 is an elevational view of the transparent Window cover mountedon a conventional window sash.

FIGURE 3 is a detail sectional View taken on line 3-3, FIGURE 1, showingthe openable ap portion.

FIGURE 4 is a detail view of the co-acting fastener strips.

FIGURE 5 is a fragmentary perspective view of the invention mounted in awindow.

Referring to the drawings, denotes a conventional window frame havingthe usual sash opening receiving the window 12.

The window cover 14, is made of a sheet of any suitable flexible,transparent plastic material, as for example, polyethaline, that isdimensioned to snugly t the window frame 10, either on or Within thesame, as shown in FIGURE 2.

The cover 14 is comprised of having a flat panel 14a and havingperipheral side edges 14h and top and bottom edges 14e which are turnedinwardly to form a ange which is perpendicular to the panel 14a, aseparable fastener element.

Formed 'within the body of the cover 14 is a flap 16, the sides 18 andtop 20 of which are cut from the cover such that the bottom of the apwill provide a hinge connection as will be readily apparent. A slidefastener 22 serves to detachably connect the sides 18 and top 20 of theflap to the body of the cover, the slide fastener having a-nger grippingtab (23) on the slide 24 being vcover 14 to the outside of the window byfreeing the flap 16 which may be, swung down. Such an access opening inthe cover 14 formed bythe ap 16 is desirable for many'purposes such asaccess to the window lock, to open the window for ventilation and topermit passage of objects therethrough without removal of the cover 14.It is to be understood that the flap 16 may be formed of triangularshape with two free sides or in part of any desired shape, rectilinearor curved.

To secure the window cover 14 to the frame molding, a separable fastenerof the type known as VELCRO is employed. This type of fastener employstwo like tiexi ible strips 30, see FIGURE 4, of a fabric or othersimilar material that constitutes a backing for a dense, fibrous orthread-like nap 32. When the strips 30 are brought into'contactingengagement under slight pressure, the naps 32 will interengage and/ orinterlock to hold the stripsV 30 tightly together. Separation of thestrips 30 is effected by simply pulling the strips apart.

Thus, for the purposes of this invention, one nap-carrying VELCRO strip30 is secured to the outside side of the ange formed by edges 14b and14C of the flexible plastic window cover 14 in any desired manner knownin the art as by a Dermal bond, adhesives, stitching, etc. The other andcomplemental VELCRO strip 30 is secured in any desired manner as byadhesives, tacks, etc. tov the inner edge 25u of the window framemolding 25.

To apply the flexible, transparent plasticV window cover 14 to thewindow, the naps 32 of the VELCRO fastener strips are carefully alignedand simply pressed together. This will securely hold the window cover 14in place and will also provide an airtight seal. Removal of the windowcover 14 from the window is effected by simply pulling theperimeter edgeportions of the same away from the nap carrying strip 30 that is securedto the window frame molding 25. This pulling away of the window cover 14is facilitated by providing along the bottom of the cover 14, and on theinside thereof, a pair of hand-holds or grips 34.

The flexible, transparent plastic window cover 14 with attached fastenerstrip 30 may be readily rolled into a roll for either storage ortransport.

It will be seen that the flexible, transparent plastic window cover 14and its mode of attachment to a window frame molding, along with itsseparable -ap 16 makes for a very effective, cheap and efficient stormwindow. The window cover 15 is readily adaptable as a cover for windowsor other structural openings of a variety of shapes as will be apparent.'The cover 14 also has application as a removable closure for purposesother than forwindows as set forth above as such a cover of eXiblematerial, plastic or otherwise, transparent or not, employing a VELCROfastener, is applicable for closets, doorways, display windows orcabinets, etc.

While certain novel features of my invention have been shown anddescribed and are pointed out in the annexed claim, it will beunderstood that various omissions, substitutions and changes in theforms and details of the device illustrated and in its operation can bemade by those skilled in the art without departing from the spirit ofthe invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

For use with a vwindow frame and a window sash mounted therein, areadily attachable and removable interior window cover comprising:

(a) a flexible sheet of transparent p lastic material,

(b) a continuous flange of uniform width formed integral with saidsheet, extending completely around the perimeter thereof and normalthereto,

(c) said sheet and ange corresponding in length and width to the insideof said window frame so as to closely t therein,

(d) an engageable and disengageable strip fastener means between saidflange and window frame for securing said sheet thereto,

(e) said strip fastener means comprising a pair of continuous stripelements each having an exposed nap formation provided on one sidethereof,

(f) one strip element being secured to said window frame completelyaround its inside perimeter normal to the window sash and the otherstrip element being secured to the outer face of said flange, whereby onpositioning of the sheet with its ange directed away from the windowsash within the window frame and placing the strip element on the angethereof in opposed contacting relation to the window frame strip elementand applying pressure thereon, said nap formations will interlock tosecure the sheet in xed position within said window frame,

(g) a pair of nger hold means at the lower side of said sheet adjacentto and inwardly of the flange thereat,

(h) a flap cut out from said sheet having parallel vertical sides and ahorizontal top side, the lower side of said flap forming a hingeconnection with said sheet adjacent to the lower side thereof and abovesaid linger hold means,

(i) slide fastener means securing the free vertical sides and top sideof the flap to said sheet, and

(j) said ap when disconnected from said sheet providing an accessopening therein.
